Rising Gas Prices Hit Western States and Large SUVs Hardest

Average annual fuel costs in the U.S. increased by $706 between January and April 2026, according to data from iSeeCars. Wyoming drivers saw the highest statewide rise at $1,029, while Toyota Sequoia owners in Tennessee experienced the largest model-specific jump, with costs climbing by $2,190.

State-level increases varied widely, ranging from $487 to $1,029 during this four-month period. iSeeCars reported that 23 states exceeded the national average increase.

Wyoming residents faced the steepest climb, with average annual fuel costs rising from $1,837 in January to $2,866 in April. Utah followed with a $967 increase, while Arizona and Idaho saw rises of $963 and $956, respectively.

Why are some states seeing higher fuel cost increases?

Higher annual mileage combined with rising pump prices drove the costs up in Western and rural states. Wyoming drivers averaged 15,200 miles per year, according to the study. In contrast, New York drivers averaged 10,541 miles, resulting in the nation’s smallest increase of $487.

Karl Brauer, an executive analyst at iSeeCars, stated that drivers in Western states like Wyoming and Utah, along with those driving large SUVs, suffered more than the average consumer. He noted that “wide-open spaces and SUV-heavy fleets” in those regions made the price hikes more expensive for residents.

The data shows that states with moderate gas prices but high mileage can experience larger cost jumps than expensive fuel markets where residents drive less. Hawaii, for example, saw a $499 increase with an average of 10,469 miles per year.

Which vehicles are most affected by rising gas prices?

Full-size family SUVs and large utility vehicles faced the heaviest financial impact. Toyota Sequoia drivers in Tennessee saw estimated annual fuel costs jump from $4,095 in January to $6,285 in April, a $2,190 increase.

Nissan Armada owners saw some of the largest increases in states including Oregon, Utah, Washington, Arizona, and California. Similarly, Chevrolet Suburban drivers across the Midwest, Northeast, and South faced significant cost hikes.

Brauer described the combination of big SUVs and long driving distances as “expensive” during price spikes. He noted that low gas prices in some states aren’t enough to offset the costs of “thirsty vehicles.”

What happens next for vehicle shoppers?

Consumers may place a higher priority on fuel economy when choosing their next vehicle. Those who drive high annual mileages could be more likely to weigh fuel efficiency alongside the initial purchase price.

Shoppers might also shift their focus toward genuine vehicle needs rather than size. This trend is likely to intensify for residents in rural-driving states where the financial burden of large SUVs is most pronounced.
